“Investors simply seized on the company’s upbeat sales forecast ahead of the trade show as a reason to pick up a bargain during trading,” Shih said.

Asustek shares had fallen 9.88 percent in the previous two trading sessions after International Data Corp (IDC) said worldwide PC shipments in the first quarter fell 13.9 percent from a year earlier to 76.29 million units.

The 13.9 percent plunge was the steepest quarterly decline since IDC first started to track the global PC market on a quarterly basis in 1994.

Shih said because concerns over the PC market’s outlook still remain, Asustek shares are expected to move in a narrow range.
